Butylscopolamine Bromide

Butylscopolamine bromide, also known as hyoscine-N-butylbromide, is a muscarinic antagonist that acts to prevent acetylcholine-stimulated contraction of smooth muscle in the gastrointestinal tract. It is used to treat abdominal cramping and pain, motion sickness, postoperative nausea and vomiting. It is also used for diagnostic procedure on eyes, mydriasis induction and cycloplegic refraction, uveitis, and iridocyclitis. Butylscopolamine bromide is also used in the treatment of delirium tremens. Butylscopolamine bromide injection (hyoscine butylbromide) is indicated for the relief of acute genitourinary or gastrointestinal spasm (renal or biliary colic), or to produce smooth muscle relaxation prior to radiological procedures such as pyelography or other diagnostic procedures where spasm may be a problem (gastroduodenal endoscopy).
